When choosing a universal wheel, the material is the primary factor to consider. Common universal wheel materials on the market include rubber, polyurethane (PU) and plastic. Rubber universal wheels are tough and have excellent wear resistance. They can effectively buffer vibrations, reduce bumps and extend service life on rough and uneven surfaces, such as stone roads and gravel roads. Polyurethane universal wheels are ideal for use on smooth surfaces such as indoors or airports due to their quiet and smooth characteristics. They produce almost no noise when pushed and have low rolling resistance. Although plastic universal wheels are relatively cheap, they have poor wear resistance and are only suitable for short-distance and light-load use scenarios. Long-term use is prone to wear and deformation.
The structural design of the universal wheel will also directly affect the user experience. High-quality universal wheels mostly use a double-bearing structure. This design makes the wheel more flexible when turning and greatly reduces resistance. Even turning and turning operations in narrow spaces can be easily completed without jamming. In addition, the connection between the wheel axle and the luggage trolley is crucial. The metal connector can effectively prevent loosening and breaking caused by frequent steering with its high strength and stability, ensuring the safety and stability of use.
There are various types of brake systems, each with its own characteristics. The foot-operated brake is a more common one. It is very convenient to operate. You can achieve rapid braking with just a light step of your foot. It is suitable for scenes that require frequent parking. The handbrake brake is similar to the bicycle brake. The braking force is controlled by pulling the handle. It is not only simple to operate, but also can flexibly adjust the braking force according to actual needs. It is especially suitable for long-term fixed luggage trolleys. The side brake brake has a relatively simple structure and a small size. It is mostly used in lightweight luggage trolleys. Although the braking force is relatively weak, it is easy to use and does not take up too much space.
Different usage scenarios have different requirements for the universal wheel and brake system of the luggage trolley. If you often use it outdoors or on uneven roads, large-sized, wide-tread universal wheels are the best choice. Large-sized wheels can better cross obstacles, and wide treads can increase the contact area with the ground and improve passability. At the same time, it is necessary to equip it with a brake system with strong grip, such as a foot-operated brake with anti-skid patterns, to ensure that it can park steadily on slopes and uneven roads. When used on smooth roads such as indoors and at airports, silent and smooth universal wheels and convenient handbrake systems can better meet the needs. They will not produce noise to affect others, and are also convenient for fixing the luggage trolley at any time.
The load-bearing capacity of the luggage trolley is closely related to the durability of the universal wheels and brake system. When choosing, you should match the appropriate universal wheels according to the maximum load-bearing capacity of the luggage trolley. Once overloaded, it is easy to cause the wheels to deform and damage, affecting normal use. For the brake system, we should pay attention to its material thickness and spring elasticity. Metal brake pads are more wear-resistant and durable than plastic brake pads; high-strength springs can ensure that the brake system still maintains good elasticity and braking force under frequent use.
Safety details should not be ignored during the purchase process. When purchasing, be sure to test the steering performance of the universal wheel in person to ensure that the wheel can achieve 360-degree flexible steering and there is no abnormal noise or jamming during the rotation process. For the brake system, we should check whether its braking effect is sensitive and reliable. Place the luggage trolley on a slight slope. After starting the brake, observe whether the luggage trolley will slide to judge the stability of the brake. At the same time, we should also pay attention to the fit between the brake and the wheel to avoid empty space and affect the braking effect.
Later maintenance is essential to extend the service life of the universal wheel and brake system. In daily use, the universal wheel and brake system should be cleaned regularly, and the hair, silk thread and attached debris wrapped around the wheel should be removed in time to prevent these foreign objects from affecting the rotation of the wheel and the normal use of the brake. If the universal wheel is found to be stuck, you can apply a proper amount of lubricant to improve it. For the brake system, if the spring loses its elasticity, resulting in a weakened braking force, the spring should be replaced in time to ensure that the brake system is always in good working condition.
